Thistle, Primal Riftborn

Convoke
While it's Day, this creature has Defender. When
this creature attacks and is blocked, this creature
also deals it's damage to creatures adjacent to the defending creature.
Stop making excuses, Cobalt. If you want something,
take it. If someone tells you no, throw them aside.
That's how you get what you want. So keep your goal
in mind, plant your feet, grit your teeth, and TAKE
IT
